Preheat oven to 375 F degrees.
Mix melted butter with sugar and graham crackers. Stir to evenly distribute crackers into the butter.
Press mixture into pie plate or pan about 1/8 inch thick on the bottom and work up the sides.
Bake for 5 minutes. Remove from oven and let stand and cool before adding pie mixture.
* For a larger crust (10-11 inch), increase butter to 6 T. and graham crackers to 2¼ c.
